Se posiciona como una instancia de reunión para todo el alumnado de las carreras de Geología en Chile, que incentiva la interacción entre pares, el intercambio conocimientos científicos, la construcción de plataformas de trabajo, la discusión del rol de las Geociencias en la sociedad del futuro y también la discusión de problemáticas específicas y transversales que afectan a los estudiantes en el país. La VIII entrega de esta noble reunión tiene como sede oficial la Región de Atacama, siendo conducida por los estudiantes de la Carrera de Geología Universidad de Atacama, casa de estudios que además celebra su décimo aniversario de fundación de la carrera. Instalado en el margen más austral del desierto más árido del mundo, la geología, los contrastes y bellezas cautivantes de Atacama reciben a los más de 400 participantes con fraternidad, alegría y orgullo. Esta instancia además, resalta cuán fundamental es la interacción Geociencias- sociedad, en el contexto de una Región fuertemente azotada por los más grandes aluviones de los últimos 20 años en el Norte de Chile (Marzo 2015 y Mayo 2017). La presente versión ENEGeol 2017 es el resultado del trabajo incesante y desinteresado de un gran número de alumnos, profesores, autoridades e instituciones. Con ello, en este Libro de Contribuciones se presentan 30 investigaciones inéditas, que se suman a las 32 conferencias ofrecidas por alumnos e investigadores, 4 cursos especializados y 9 visitas a terreno al interior de la Región. Esperamos que los recuerdos de este encuentro perduren a través del tiempo geológico.

I will provide information about Chile as country, breaking down several crucial regions to highlight the key threats to each. Several natural disasters used in my research will be defined and a brief account of their occurrences throughout the country’s history will be given. My paper will demonstrate how Chilean society has shaped their way of life around these economic consequences, with a unique look at the short-term effects on small businesses. The primary focus will be on how the economic impact of an exogenous variable, such as a natural disaster, varies based on certain endogenous variables such as location and prosperity.

  • Gas Hydrate Versus Seabed Morphology Offshore Lebu
    www.nature.com/scientificreports OPEN Gas hydrate versus seabed morphology ofshore Lebu (Chilean margin) Iván Vargas‑Cordero1*, Umberta Tinivella2, Lucía Villar‑Muñoz3,4, Joaquim P. Bento5, Carolina Cárcamo6, Diego López‑Acevedo5, Francisco Fernandoy6, Alessandra Rivero6 & Marion San Juan6,7 Gas‑hydrate occurrences along the Chilean margin have been widely documented, but the processes associated with fuid escapes caused by the dissociation of gas hydrates are still unknown. We report a seabed morphology growth related to fuid migration ofshore Lebu associated with mud cones by analysing oxygen and deuterium stable water isotopes in pore water, bathymetric, biological and sedimentological data. A relief was observed at − 127 m water depth with fve peaks. Enrichment values of δ18O (0.0–1.8‰) and δD (0.0–5.6‰) evidenced past hydrate melting. The orientation of the relief could be associated with faults and fractures, which constitute pathways for fuid migration. The benthic foraminifera observed can be associated with cold seep areas. We model that the mud cones correspond to mud growing processes related to past gas‑hydrate dissociation. The integration of (i) the seismic data analysis performed in the surrounding area, (ii) the orientation of our studied relief, (iii) the infaunal foraminifera observed, (iv) the grain size and (v) the total organic matter and isotope values revealed that this area was formerly characterised by the presence of gas hydrates. Hence, this part of the Chilean margin represents a suitable area for investigating fuid‑migration processes. Along continental margins, morphological features associated with fuid escapes such as mud volcanoes, mud mounds, pockmarks, seeps, precipitates—carbonates and hydrates-, piping/rills and brine pools have been reported worldwide (e.g.1–7).

  • Tectonic Implications of Late Cenozoic Sedimentation from the Coastal Cordillera of Northern Chile (22-24"S)
    Journal ofrhe Geological Sociery, London, Vol. 152, 1995, pp. 51-63, 11 figs, 1 table. Printed in Northern Ireland Tectonic implications of Late Cenozoic sedimentation from the Coastal Cordillera of northern Chile (22-24"s) A. J. HARTLEY' & E. J. JOLLEY2 'Production Geoscience Research Unit, Department of Geology and Petroleum Geology, University of Aberdeen, Aberdeen AB9 2UE, UK 'BP Exploration, Farburn Industrial Estate, Dyce, Aberdeen AB2 OPB, UK Abstract: Late Cenozoic sediments from northern Chile (22-24"s) are exposed on the coastal plain between the Coastal Cordillera to the east and tilted fault blocks of the Mejillones Peninsula to the west. During the mid-Miocene to Pliocene (?up to mid-Pleistocene) a shallow marine basin developed unconformably over basement. Sedimentation was initially restricted to a small half-graben on the western margin of the Mejillones Peninsula during the Miocene. Expansion of the basin during the early Pliocene resulted in widespread shallow marine sedimentation across the study area. Alluvial, aeolian and beach sediments were restricted to the basin margins, where sediment was supplied from the Coastal Scarp (a major cliff-line bounding the western margin of the Coastal Cordillera) and isolated(islands) fault blocks. Areas of restrictedclastic input were characterized by carbonate deposition. Marine planation surfaces or terraces (0.5-600m elevation) and associated palaeo-sea cliffs cut intoMiocene-Pliocene sediments and basement rocks, developed along the coastline of northern Chile in the ?late Pliocene to late Pleistocene. A similar age for a number of late Pleistocene terraces (125 OOO years) now at different elevations, suggests that they were cut during interglacial highstands (oxygen isotope stage 5).

Lara2 1 United States Geological Survey, Cascades Volcano Observatory, 1300 SE Cardinal Court, Vancouver, Washington, 98683, USA. [email protected] 2 Servicio Nacional de Geología y Minería, Programa de Riesgo Volcánico, Avda. Santa María 0104, Santiago, Chile. [email protected] ABSTRACT. Chaitén Volcano erupted unexpectedly in May 2008 in one of the largest eruptions globally since the 1990s. It was the largest rhyolite eruption since the great eruption of Katmai Volcano in 1912, and the first rhyolite eruption to have at least some of its aspects monitored. The eruption consisted of an approximately 2-week-long explosive phase that generated as much as 1 km3 bulk volume tephra (~0.3 km3 dense rock equivalent) followed by an approximately 20-month-long effusive phase that erupted about 0.8 km3 of high-silica rhyolite lava that formed a new dome within the volcano’s caldera. Prior to its eruption, little was known about the eruptive history of the volcano or the hazards it posed to society. This edition of Andean Geology contains a selection of papers that discuss new insights on the erup- tive history of Chaitén Volcano, and the broad impacts of and new insights obtained from analyses of the 2008-2009 eruption. Here, we summarize the geographic, tectonic, and climatic setting of Chaitén Volcano and the pre-2008 state of knowledge of its eruptive history to provide context for the papers in this edition, and we provide a revised chronol- ogy of the 2008-2009 eruption.

Basement inheritance and Foreland basin progressive shallowing of an east-dipping subducting slab are important mechanisms of foreland partitioning, as Provenance dictated by the preexisting (pre-Andean) structural architecture and forelandward (eastward) advance of Late U-Pb geochronology Cretaceous arc magmatism. Previously recognized growth strata help define the timing of fold-thrust belt Hf isotopes shortening and retroarc basement-involved uplift, but the precise consequences for sediment routing remain poorly understood, with uncertainties in patterns of basin evolution before, during, and after shallowing and resteepening of the subducting slab.
